I'd absolutely love to be able to do it one day. I'm thinking of doing the Everest Base Camp trek as a starting point, apparently it's still quite a difficult climb and the views from the bottom of Everest are still pretty fantastic! Apparently these people run a really good trek taking you from Kathmandu to Lukla then on to the base camp in twenty days
